Recently, we illustrated the use of the ${\gamma}$–g absolute B(E2) values in the Davydov–Filippov model (DFM), instead of the ${\gamma}$−g B(E2) ratios,for analysing the spectral features of the (${\gamma}$${\le}$20°) deformed nuclei. Here, we illustrate the application of the absolute ${\gamma}$−g B(E2) values to the triaxial (γ${\ge}$20°) nuclei to seek the new role of the ${\gamma}$ variable in these nuclei, and to derive the underlying physics. The decrease of the absolute ${\gamma}$−g B(E2) value for ${\gamma}$${\ge}$20°, instead of an increase observed for ${\gamma}$${\le}$20° deformed nuclei is explained. The increase of B(E2, 2$_γ$ − 0$^+$$_1$ ) in spite of the negative band mixing parameter, for deformed nuclei, reveals a new view of the band mixing angle, in contrast to its role for the triaxial nuclei. The three moments of inertia in DF model, for ${}^{158}$Dyand ${}^{120}$Xe display their degree of triaxiality.
